Title
(EN) SYNTHESIS OF PHENOXYACETIC ACID DERIVATIVES
Abstract
(EN)

The present invention relates to an improved process for the preparation of substituted 2-(4-carbonylmethoxy-optionally 2,5-disubstituted-phenyl-acetaldehydes, in particular 2-(4-alkoxycarbonylmethoxy-optionally 2,5-disubstituted-phenyl)-acetaldehydes and their use in the synthesis of optionally substituted 2-[4-[2-[[-2-hydroxy-2-(4-hydroxyphenyl)-1-methylethyl]-amino]ethyl]-optionally 2,5-disubstituted-phenoxy]acetic acid derivatives or the salts thereof, which may be used as pharmaceutically active substances.
